list_namespaced_event with resouce_version and resource_version_match not working as expected #2151
Closed as not planned
Description
What happened (please include outputs or screenshots):
I try to get events with a resource_version older than a specific version and that does not seem to work as expected. I always get all the events. See code example where i try to demonstrate the issue.
In the first run i get all events. In the second run i try to get events only older than the oldest version - 50
What you expected to happen:
Second run should only have returned 50 events?
I might have completely misunderstood this api so feel free to close if this is expected.
How to reproduce it (as minimally and precisely as possible):
from kubernetes import client, config, watch
from kubernetes.client.rest import ApiException
import os
def pull_k8s_events(last_resource_version):
print(f"\tGetting the events NotOlderThen {last_resource_version}")
config.load_config()
api_instance = client.CoreV1Api()
namespace = 'my-namespace'
first_event_version = None
last_event_version = None
events = api_instance.list_namespaced_event(namespace, resource_version=last_resource_version, resource_version_match="NotOlderThan")
for event in events.items:
resource_version = event.metadata.resource_version
#print(f"{event.event_time if event.event_time is not None else event.last_timestamp} {event.metadata.name} {event.message} {event.metadata.resource_version}")
if first_event_version is None or resource_version < first_event_version:
first_event_version = resource_version
if last_event_version is None or resource_version > last_event_version:
last_event_version = resource_version
print(f"\tNumber of items retrieved: {len(events.items)}")
print(f"\tFirst Event Version: {first_event_version}")
print(f"\tLast Event Version: {last_event_version}")
return last_event_version
print(f"[Main]: init")
last_resource_version = pull_k8s_events(0)
new_resource_version = int(last_resource_version) - 50
print(f"[Main]: new resource version: {new_resource_version}")
pull_k8s_events(new_resource_version)
print("Ended.")Anything else we need to know?:
I tried this against kind 1.27 and eks 1.28
